-----------------------------------
Summary: YarnAuthorizationProvider AccessRequest has Null
RemoteAddress in case of FairScheduler
Key: YARN-9920
URL: https://issues.apache.org/jira/browse/YARN-9920
Project: Hadoop YARN
Issue Type: Bug
Affects Versions: 3.3.0
Reporter: Prabhu Joseph
Assignee: Prabhu Joseph
YarnAuthorizationProvider AccessRequest has Null RemoteAddress in case of
FairScheduler. FSQueue#hasAccess uses Server.getRemoteAddress() which will be
Null when the call is from RMWebServices and EventDispatcher. It works fine
only when called by IPC Server Handler.
FSQueue#hasAccess is called at three places where (2) and (3) returns NULL.
1. IPC Server -> RMAppManager#createAndPopulateNewRMApp -> FSQueue#hasAccess ->
Server.getRemoteAddress returns correct Remote IP.
2. IPC Server -> RMAppManager#createAndPopulateNewRMApp ->
AppAddedSchedulerEvent
EventDispatcher -> FairScheduler#addApplication -> FSQueue.hasAccess ->
Server.getRemoteAddress returns NULL.

Have verified with CapacityScheduler and it works fine.
